What happens if you were to flash a completely stock kernel and then flash 3b.

Nah. The stuff you are referring to I believe is just bad blood. It's unfortunate but it happens and it's whatever. Try flashing the stock kernel and then flashing this when u get a second.

I also show as ENFORCING - NOT permissive like some phones apparently do - I am on 4b.2 ???

On another subject, I am using ROM TOOL BOX to manage CPU and VOltage - TRICKSTER doesn't register Frequencies or Voltages - I am wondering is there a preferred APP for managing frequencies and stuff on this kernel? Or is ROM TOOL BOX good enough?

I'm back on 3b, are there any major differences between 3b and 4.2b? If you have time to share.

I'm trying to decide which kernel to flash and I'm wondering if this one does anything to improve the sound (make it louder). I know there's a volume hack but I'd rather flash one thing, as opposed to 2

My understanding is that any sound mods will be made in the rom/system. Not the ram disk/kernel. . But I could be wrong.

No this kernel and all other note3 kernels currently have no sound modifications in place. I'm sure faux sound or the devs own iteration will be implemented soon. Otherwise their is plenty of sound hacks and or apps to help do what u need.

Well I just flashed the sound mod (which is AWESOME, by the way) so I guess I'll flash a kernel and see what happens.

    leanKernel is not for everyone. My philosophy is to keep the kernel footprint as small as possible by trimming as much fat as possible, and at the same time keeping it stable, power efficient, and fast. You will find that it's lacking some of the bells and whistles of other custom kernels, so if you like features you came to the wrong thread. :)

    The "warranty bit" message at boot is normal.

    FAQ

    What are ondemandX and interactiveX?
    ondemandX and interactiveX are very very close to "stock" ondemand and interactive governors, respectively. The only difference is screen_off_maxfreq sysfs support. This means that it gives you the ability to limit phone's max frequency when screen is off. This feature could be effective in reducing battery usage, especially if you have a misbehaving app (or two) that consume cpu cycles while screen is off. The default value is 1267200 - if you change the value to your top speed you're effectively disabling the feature and restoring stock behavior completely. You can use an app like Trickster to modify screen_off_maxfreq.
    Code:
    cat /sys/devices/system/cpu/cpufreq/interactive/screen_off_maxfreq
    1267200

    What is this purple hue/push issue, and do I care?
    First if you don't already know about it then you're better off not discovering this. So ignore and move on. :)
    Otherwise, read this thread: http://xdaforums.com/showthread.php?t=2462078
    On leanKernel, you can set panel temp to -25 or lower, or panel color to 3 or higher to fix/circumvent this issue.

    mpdecision on or off?
    leanKernel (for all phones) is a drop in replacement for stock kernel. It is designed to work with mpdecision - I would not turn it off. But then again if you like how the phone is running with it off, go ahead. :)

    my cores are stuck!
